Yeah, nope. This is just nonsense. Plasma cosmology as defined by Alfven was an expanding cosmology where the universe was driven to expand by matter anti-matter annihilation. If you replace the expansion with tired light, there is nothing left. It's not plasma cosmology. PC could not even fit the observations of the universe in the 80s, much less today. There is a reason it is literally dead as a topic of research. It offers no quantative fit for most of the things LCDM can match, (galaxy clusters, large scale structure, the light element abundances, gravitational lensing...). Plasma cosmology did not predict a Cosmic Microwave Background, like the hot big bang did. Alfven's post hoc guess that it was Galactic emission was ruled out by COBE and the imprints of galaxy clusters. Note that CDM correctly predicted the detailed fluctuations of the CMB, something no alternative model can do.

Secondly tired light has been tested and ruled out many times. Firstly there are zero known processes which could cause redshift, all known processes either scatter the light in angle or have wavelength dependence. Which is not observed. The nail in the coffin is that with redshift there is cosmic time dilation, measured in supernovae and quasars. There is no tweaking this. It fails a simple empirical test.

Occam's Razor does not tell you any of this, this is just your personal bias. At best Occam's Razor says of two models of equal explanatory power, the simpler one (fewer assumptions) is preferable. Well we have seen that PC and LCDM are not of equal explanatory power, LCDM is far more predictive. It's not simpler either, as it contains two large assumptions (tired light effect, half anti-matter), the same number as LCDM. And as I said, tired light has already been rejected.
